Nikki, I have had 50% or a little better hatch with shipped eggs. I am super careful with temp and humidity and I rarely candle. I also use an egg turner and this year added a fan to my Little Giant styro bator. I had much higher hatch rate with some of my local friends eggs. This year I ordered a dozen + splash marans eggs and ended up with 8 chicks, a dozen + golden cuckoo marans and again, 8 chicks. I ordered 8 + dark brahma eggs, hatched 4 chicks and lost 1. The DB eggs had a lot of bad air cells and I don't know if they were old eggs, infertile, or if I have the USPS to thank for poor handling. I had a bunch more eggs develop until the end but not hatch. I know my humidity was high, temp was good so I don't know what happened. I might try hatching in egg cartons with the bottoms cut out as previously suggested. Maybe the other chicks didn't like being rolled around by the new hatches.
I have a question. What do people use for "hatchers"? I have several small incubators. Next week they will be pretty full. If somehow I end up with a higher hatch rate, I'll have Silkies coming out my ears next month. Woo Hoo! What a thought!
